NF3 Ultra-D 939/AGP

[doompc]

Back to 711, C19 was setting "FSB" to 217MHz automaticaly...

Could someone please help me with the following.

I can't get the board to run Dual Channel mode with two sticks of Gskill TCCD and an HTT of 215Mhz or higher. It wil boot, but during the loading screen of Windows XP i'll get nice BSOD. Even with the most relaxed timmings (like 3-4-4-8 @ 2T) it's a no go.

 

My 2x512MB TCCD will complete 40 runs of Test 5 and 8 of MemTest flawlessly with the following settings:

10x285HTT, vdimm 2.8 2.5-4-3-7 @ 2T in dual channel mode (yellow and orange slots both seem to work)

 

So it seems to me those two sticks themself are stable.

 

With one stick I can boot into Windows running on 10x285 2.5-4-3-7 @ 1T and everything works perfect.

I've been swapping the sticks in the yellow and orange slots, upping vdimm etc. Using dividers will result in no post at all, or BSOD's again

 

What the deal here? i'm really running out of options

 

Btw, my Gskill ran perfect on my old nF3 UT 250GB (10x290 2.5-3-3-7 @ 1T)

 

(offcourse LDT = 3x and 1.75v)

Are you trying to run@1:1. Have you tried 5/6 or 3/4 ratios?

[DemonEyez_NL]

I'v tried running ratios, but when i use the 6:5 divider and I go into memtest to check the correct MHz for the ram it most of the time is on 200MHz when it should be 235MHz for instance or my system wil not even post. So there'e something wrong when running dividers.

I think I should be able to do 230HTT running 1:1 at least.

 

I've installed some Kingston Hyper X temporarely and i'm now running 2x512MB at 10x280HTT (6:5) 235MHz 2.5-4-4-8 @ 1T. So go figure?

 

It seems to me there's something wrong with my two sticks of Gskill. But the strangest thing is when I test those two sticks in MemTest they give absolutely no errors and I can do 50 passes on Test 5 and Test 8, running 2x512MB at 10x280 (1:1) (2.5-4-3-7 @ 2T or running 1x512MB at 10x280 (1:1) (2.5-4-3-7 @ 1T

Sometimes the frequency isn't always what it you think it should be when using a divider. At this site you can check what your memfreq is corresponding to your HTT/divider:

[TheGeekMistress]

when running a mem bus divider, the mem bus divider defualts to the whole number of the multi. so if you're running, say a 10.5 multi and a 166 (5/6) mem divider you'll end up with it rounding down.... so lets take a 2887.5mhz 10.5x275HT bus divide by 6 times by 5 = 229mem bus.... the divider will take it like 11x262.5HT bus then divide by 6 time by 5 = 218.75. so your mem is really running at DDR438 instead of DDR458 like it would be with 10.5x275HT bus. odd huh

i wonder if it'll be like that with my new LP UT NF3 250GB 754 chipset as well. i haven't gotten the cpu for it yet so i can't find out for myself. anyone else know?

[DemonEyez_NL]

Thanx for all your responses guys, but i'm aware of divider table.

But that doesn't explain the fact that I can run my Kingston Hyper X with a HTT of 280 and an 6:5 divider (which results in 233Mhz for the ram) but My Gskills will refuse to work with those exact same settings and also crap up the divider table. (btw, I never usehalf multi's)

 

I used the Kingston Hyper X as an example to explain that with other memory than my Gskills the systeem runs fine and uses the correct mem frequency and dividers.

 

It's also no problem to run the Kingston HyperX at 10x235 (1:1) , but yet with my Gskills the system will again refuse to work at those exact same settings

 

But when I test those two Gskill sticks in MemTest, I recieve no errors and can run them up to 280HTT (1:1) doing like 40 passes with Test 5 and Test 8

 

 

So in short:

 

2x512 Hyper X at 10x280HTT (6:5) 233MHz (2.4-4-4-8 @2T) runs fine

 

2x512 Gskill at 10x280HTT (6:5) 233MHz (2.4-4-4-8 @2T) no boot, BSOD

 

2x512 Hyper X at 10x235 HTT (1:1) 235MHz (2.4-4-4-8 @1T) runs fine

 

2x512 Gskill at 10x235 HTT (1:1) 235MHz (2.4-4-4-8 @1T) no boot, BSOD

 

2x512 Gskill at 10x280HTT (1:1) 280MHz (2.4-4-4-8 @2T) MemTest gives 40 passes in test 5 and 8, but Windows will refuse to boot and gives BSOD's during loading screen

 

(btw, on my old Lanparty nF3 250Gb my two Gskill sticks ran fine at 10x290HTT (1:1)

 

 

 

@ Stef@n

I've send you a PM

Always have to remember.. Just because it worked great, good. even bad on a previous setup.. Doesnt quarantee it will work on anouther setup the same.. May be better may be worse.

[smolt]

Any body know any were in the states that has a nf3 Ultra 939 agp board in stock ?

[TheGeekMistress]

i couldn't find one, and i looked for at least a month..... they're just gone. that's what made me decide to go with the nf3 250 754

I know, I know... but come on! the Kingston is working fine and with those Gskills I can't even do more than 215Mhz. I realy feel like i'm missing something here.
